' UNITED STATES HERBERT STANLEY BRUCKS HAW, OF BOLTON, ENGLAND.

REENFORCED CONCRETE FOR SAFES, STRONG ROOMS, AND THE LIKE.

Application filed June 1, 1927, Serial No. 195,739%-, and in Great Britain June 11, 1926.

This invention relates to reenforcements for concrete for use in safes, strong rooms and the like, of the type in'which rows of interwoven spirals are interwoven with one another, and has for its object to strengthen the reenforcement against burglarious attack by the blow pipe or other means.

In accordance with my invention, I cause some or all of the said spirals, as they are being woven into the mattresswhich constitute the reen'forccmont, to be threaded through anchor bars, "which may be in the form of plates, tubes, rods, bars or the like having holes therein spaced to correspond with the pitch of the convolutions of the spirals for the passage of the coils or spirals. The said plates, tubes, rods, bars or the like (herein- 7 after termed anchor bars) may extend from top to bottom or side to side of the reenforcement, and each anchor bar is'of such dimensions as to accommodate its engagement with and bythe coils as aforesaid.

The anchor bars are preferably formed from suitable sections of 'metal capable of affording resistance to blow pipe attack. The said sections may be arranged adjacent an end or side of the reen'forcement mattress so that a plate or plates can be attached thereto to form a metal liner on the reenforcement.

Referring to the two accompanying sheets of explanatory drawings Figures 1, 2, 3 and 4 are plan views showing four arrangements of anchor bars, such bars being made from steel angle or girder sections.

Figure 5 is an elevation and Figure 6 aplan showing the application of the invention with another form of anchor bar.

The same reference letters in the different views indicate the same or similar parts.

In each of the examples given-at Figures 1 to 3, the anchor bars as a have coils or spirals as b threaded through apertures in the web or central portion of the bar, the said apertures being spaced to correspond with the l venient manner.

In the example given at Figure 4, an anchor bar is arranged as illustrated in connection with the two outer rows of spirals. A plate 0 is attached to the bar of one row.

The anchor bars a in the arrangement shown at Figures 5 and 6, extend through the central spacesof a pair of adjacent interwoven coils b as indicated, the bar having apertures cl to permit of the threading of the coils therethrough.

' What I claim is V 1. In'reenrorced concrete for safes, strong rooms and the like, the combination with interwoven rows of interwoven metal spirals, of anchor bars with apertures therein correspending with the pitch of the convolutions of the said spirals, parts of the anchor bars projecting into spirals'which are threaded. through the said'apertures.

2. In reenforced concrete for safes, strong rooms and the like, the combination with interwoven rows of interwoven metal spirals, of anchor bars with apertures therein-correspending with the pitch of the convolutions of the said spirals, the anchor bars extending into and parallel with the axes of the spirals, I which are threaded through said apertures, and having parts projecting beyond the end row of spirals, and plates forming covers or liners for-the reenforcement attached to said projecting parts. i I I V In testimony whereof I have signed my name to this specification. i
